MILL FOR HULLING CORN.

SPECIFICATION forming part of Letters Patent No. 313,997, dated March 17, 1885.

Application tiled April 1, i884. (No model.)

To all whoml t may concern:

Be it known that I, CHARLES S. DAY, of Waverly, in the county of Baltimore and State of Maryland, have invented certain Improvements in'Mills for Hulling Corn, of which the followingis a specification.

In the accompanying drawings, forming a part hereof, Figure IA is a ylongitudinal section of the improved mill. FigJIIisa erosssection of Fig. I taken on the dotted line x m. Figs. III to IX, inclusive, are views of parts of the invention on an enlarged scale.

Ais a cylindrical casing or shell supported in any suitable manner on a frame. B.

C is a revoluble shaft extending entirely through the casing A,having bearings a, which rest in boxes b on the frameV B. The portion of the shaft C inclosed within the shell A is grooved longitudinally from one end to a point near the other, and the grooves, which are denoted in the drawings by e, are dovetailed, or wider at their bottom than at the surface of the shaft. f

D D are knives adapted to tit in the grooves c, and E E are blocks inserted in the said grooves to separate the knives,as shown in Figs. LVIII, and IX. The knives D and the separatingblocks E in each groove c are secured together by abolt, F, which is passed through them, its

head resting in a pocket in a lug which closes one end of the groove. The arrows shown in Fig. 1I indicate the direction of revolution of the shaft C. The front edge and the periphiilled, scrape the hull or outer covering from the corn, which escapes from slots d near the bottom of the casing. The corn is fed' to the mill through a hopper, G, and the hulled product is removed from the casing, after the oompletion ofthe hulling process. through an opening, e, which is provided with a door, f. The hulled corn and the hulls or waste product fall to the iioor or to any suitable receptacles placed under the mill, and are separated by a partition, g.

I claim as my invention- In a mill for hulling corn, astaiionary shell combined with a revolu ble shaft, the said shaft having longitudinal dovetail grooves open at one end and closed at the other, and at'the closed ends provided with pockets, a series ot' knives and separating-blocks'in the grooves, and bolts which pass through the said knives and blocks, each having a nut atone end and a head at the other, the said heads resting in the said pockets, substantially as specified.

CHARLES S. DAY.
